Sujet: New measurement of the CP violating parameter sin(2*beta) at CDF and
future prospects
Par: Prof. Franco Bedeschi
Resume:
A new measurement of sin(2*beta) by the CDF collaboration is
presented. This analysis is based on a sample of 400 B0 --> psi K0S events
and uses 3 different flavour tagging methods. This result improves the error
on sin(2*beta) by more than a factor 2 relative to the previously published
CDF measurement. The future physics reach of the CDF experiment on the sides
and angles of the unitarity triangle is briefly discussed.
